NORWOOD, Mass. -- (Business Wire)
Analog
Devices, Inc. today announced a low power, next-generation
biopotential analog front end (AFE) which enables smaller, lighter, and
less obtrusive cardiac monitoring devices with longer battery life. The
AD8233 AFE is a fully integrated, single-lead electrocardiogram (ECG)
front end designed in one compact, easy-to-use component. Typically,
developers need to design ECG front ends from individual components,
which can add incremental cost and design time. The highly integrated,
out-of-the-box AD8233 AFE eliminates these unnecessary costs and extra
time, helping developers get products to market more quickly.
Additionally, the device’s 2.0mm × 1.7mm tiny size enables the design of
wearable health devices that are smaller, lighter, and easier to wear.
Bulky, heavy, and obtrusive monitors can be unpleasant for patients to
wear and may even interfere with their everyday lives. Longer battery
life is another crucial attribute for cardiac monitors and is vital to
ensure continuous monitoring that provides accurate data without the
interruption of a recharge or battery replacement. The AD8233 AFE’s low
microamp-range power consumption results in greatly extended battery
life.

Along with its small size, the single-supply (1.7 V to 3.5 V) AD8233
features extremely low quiescent current of 50 μA (typical); lead on/off
detection even while in shutdown mode (<1 μA); and 80-dB common-mode
rejection ratio (DC to 60 Hz). Electrical noise, a critical
specification for cardiac-monitoring devices, is below 10 μV from 0.5 to
40 Hz. The AD8233 also allows for highly flexible filter configurations
which are essential to consistent, confident operation in an inherently
harsh electrical environment under a range of use cases: a two-pole
adjustable high-pass filter, a three-pole adjustable low-pass filter
with adjustable gain, and an RFI filter. For ease-of-use and
flexibility, it also includes an integrated right leg drive (RLD)
amplifier with shutdown plus an uncommitted op amp. Analog Devices also
offers an evaluation board, reference design, web based filter design
tool and Spice model to facilitate design-in and speed time to market.
